Interpretation of neonatal and pediatric electrocardiograms (ECG)

WebSeptal q-waves are small q-waves frequently seen in the lateral leads (V5, V6, aVL, I). They are due to the normal depolarization of the ventricular septum (see previous discussion). Two small septal q-waves can actually be seen in V5–V6 in Figure 10 (left hand side). An isolated and often large Q-wave is occasionally seen in lead III.

WebNov 20, 2024 · A pathologic Q wave is defined as a Q wave that is larger than 1/3 the height of the R wave or is greater than 2.5 mm in leads II, III, aVF, and V5-V6. A pathologic Q wave is often seen in association with an ST segment elevation, which is indicative of myocardial infarction (heart attack). WebThe three waves of the QRS complex represent ventricular depolarization. For the inexperienced, one of the most confusing aspects of ECG reading is the labeling of these waves. The rule is: if the wave immediately after the P wave is an upward deflection, it is an R wave; if it is a downward deflection, it is a Q wave:
